Python: "re" module is included in "Tkinter" module?

I'm using Python 3.6.4 with Miniconda on MacOS. I'm curious about that I can use methods that belongs to re module after I import tkinter. For example, if I want to use a re method without importing it: 

>>> re.compile('abc')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 're' is not defined

But if I use a re methods after importing tkinter, it works properly, like: 

>>> from tkinter import *
>>> re.compile('abc')
re.compile('abc')

So I can use re.compile() even if I haven't done import re. Why does it happen?

Solution

  • From the tkinter Source in line 39:

    import re

    So when you import the Module tkinter you automaticly import re with it
